So I don’t drink coffee, so I can’t for sure say this is a good deal, but it is one of the most popular coupons on Amazon, and it was just released, so I am guessing it is a good coupon! The 20% off Starbucks coupon is meant to be used with your Subscribe and Save discount. When you combine the 15% off Subscribe and Save discount (w/5 or more orders per month) and the 20% off Starbucks coupon, I am guessing you are getting a pretty good deal on these popular drinks delivered right to your door!
